LIQUID-FUEL IGNITER AND BURNER.

To all whom t may concern:

Be it known that we, JOHN CALVIN P.' KING, citizens of the United States, and residing at Grosse Point Park, county of Wayne, and State of Michigan, and Chicago, county of Cook, and State of Illinois, respectively, have invented a new and Improved Liquid- Fuel Igniter and Burner, of which the followingl is la speciiication.

This invention relates to means for igniting liquid fuels, and its object is to provide a combination of a vaporizing device, andan atomizer which will be made operative b-y the closing of a switch in an electrical circuit, with or without the use of a separate ignite'r, which device shall be simple in construction and which may be easily and read .ily combined from well known elements.`

This invention consists in the combination of a source `of atomizedfuel, preferably a fan driven by an electricV motor, which fan is attached to a carbureter, of a heating eletil() ment, preferably a trough made of a strip -of high resistance metal ,which becomes highly heated when in a proper electric circuit and positioned to receive such drops of the fuel as mayV fall from the atomizer. It alsoa consiste in combination with the atomizer and vaporizer of a spark plug adjacent the vaporizer so that a spark may ignite the vfuel It further consists in connecting the heat# ingelement andthe motor in series, con-'- necting the. primary circuit of the induction coil for the spark plug in parallel with the circuit of the motor and heating element,- and connecting a switchinto a main from which the parallel 'circuits derive their current.

In the accompanying drawing, Figure 1 is a central vertical section of this igniter and burner. Fig. 2 is a diagram showing the electric circuits. Fig. 3 isa section of the vaporizer on a larger scale. Fig. 4 is a section of a portion of the carbureter. lFig. 5 is a cross section of the vaporizer.`

- Similar reference characters indicate like parts throughout the several views.

The combustion chamber l-may be of any shape or size and may be designed' for any purpose. The carbureter 2 is of any desired type adapted for liquid fuel. Instead of drawing air through the mixing tube 3, a

' fan 4 is designed to force the air through SQUIREsand A Specification of Letters Patent.' Patented J 11119 24, 1919 applicati@ med December 17,1918. semina 267,125.

this tube and the same effect is obtained. The fuel flows through the passage 5 from a ioat chamber 6 am through openings 7 into the Venturi tube l The fan is driven" by an electric'motorQ 60 shown conventionally in Fig. 2, and fuel will collect at the discharge end of the nozzle 10 and 'drip down from the lowest point thereof, such as a lip 11, onto the heating. element 12 which is preferably a ribbon of 65 high resistance metal bent upon itself and creased to constitute' a trough, the loop 13 at the outer end yproviding for the unequal. expansions. Because of the cold liquid fuel continuing to drip down onto the vapor- `izer this element will be prevented from over-heating from the temperature of the furnace. The bolt 14 constitutes One ter1ninalof this element while the sleeve 15 conprimary winding 25 of the induction coil 85 connects to the two main wires and may. be provided with a vibrator 26. The current which passes through the motor 9 may also pass through the vaporizer 12, the wires 27 and 28vco1npleting a circuit which is par- 90 allel to the circuit of the primary r.winding ofthe induction coil.

When the switch is closed, the fan will force air through the carbureter and atom ized fuel will be thrown into the combustion chamber. At the same time, the trough 12 will become highly heated and the fuel that drips from the lip 11 on the nozzle 10 4on'to this heating element will be vaporized and this vapor, mixed with the air of the combustion chamber, will ignite which will cause thefvapor blown from the nozzle 10 to ign-ite. --The spark plug shown` in the drawing may be omitted where the proportions, current, and resistances are such that the temperature of the vaporizer becomes sufficient to ignitethe vaporized fuel.

It will be understood-that the types of' atomizer. vaporizer or spark plug form no part of the present invention and 'that any -110 desired constructions of these elements and circuits between them may be adopted so long as the vaporizer is found to receive and hold the drops of liquid which fall from the nozzle'lO until this fuel evaporates. The sizes and proportions of the various parts ma therefore all be changed by those skilled 1n the art lwithout departing from the spirit of our invention as set forth in the following claims, and any other means for producing the air currents and feeding the fuel may be employed.
